The present invention relates to Venetian blinds or shades and the like.

Among the objects of the invention is to provide a novel Venetian blind so constructed and 3 arranged as to be contracted and extended in sections.

In the usual type of Venetian blind. the means, usually ropes, for raising or contracting the blind are connected to the lowermost or bottom slat of the series of slats of which the blind is composed, so that upon pulling on the ropes the bottom slat is first raised until it contacts the next slat above which is then raised until it contacts the next slat above it and so forth.

In other words the slats pack or pile up from the lower end of the blind. Accordingly when the blind is raised part way, as for example, half way up, the packed or piled slats form a thick and unsightly pack or pile which cuts of! a considerable light and air.

It is, therefore, an object of the invention to provide novel means, such as ropes, so constructed, arranged and connected to given slats of the series of slats of the blind as to start :5 packing or piling an upper group of slats instead of at the lower end of the blind so that as the upper group of the slats are packed or piled up, the lower portion of the blind will be raised with the slats in spaced relation. As for ex- 80 ample, if the upper half of the slat series be packed or piled up, the lower half will be raised half way up without any packing or piling up of the slats thereof, the lower slat coming at about the meeting rails of the upper and lower sashes or easements of the window. In this way there is no unsightly and thick pack or pile of slats at that point. The ropes are so arranged and connected, when it is dedred to raise the blind further, asto then start packing or piling up the slats of the lower section. If the blind be composed in two sections, the latter packing or piling up will start at the bottom of the second section, that is, the bottom of the blind. If the blind be composed of three sections, the packsection, the third section being raised with the slats in spaced relation, and after the slats of the second section are all packed or piled up, then the packing or piling up of the slats oi the third or lowest section will start. The same system is used for four or more sections, it being understood the invention ccmprehends the providing of any number of sections desired.

The invention has as a further object of the invention the provision of a novel means for ing up will start at the bottom of the second supporting the suspending tapes of the blind and for tipping the slats to the desired inclination or horizontalwise.

The usual ropes for tipping the slats are or may be eliminated.

A further object of the invention is to provide a novel support at the upper end of the blind. The usual type of support comprises a thick heavy cross-piece secured at its ends to the window frame and carrying pivot brackets for pivotally supporting beneath it another thick heavy slat shorter in length than the cross piece.

These are very unsightly and ugly.

The present invention comprehends the provision of means which avoids these disadvantages, besides providing for a support which is simple in structure,

and very conveniently set in place.

Other objects, capabilities, advantages, features and the like are comprehended by the invention as will later appear and ently possessed by the invention.

Referring more in detail to the drawings the embodiment selected to illustrate the invention is shown in connection with a window comprising side frame parts or Jambs I and 2 to the inner facings of which are secured sash or casement stops or guide pieces 3 and 4, a stool 5, and a lintel stop 6.

The blind comprises a series of slats I of which the base slat 8 is heavier and thicker than the remaining slats of the series. The slats l are supported upon cross tapes 9 and 10 (Figs. 6, 7, 8 and 9) the ends of which are woven in or sewed to the suspending tapes ii and I2, the cross tapes being in staggered relation for the successive slats so as to distribute the weight of the aggregate evenly on the suspending tapes instead of along an edge portion of each suspending tape. The lower end portions l3 and ll of the suspending tapes pass under and support the baseslat 8. The upper end portions l5 and 16 of the suspending tapes pass over hollow cylinders i1 and I8 which are rotatable on a supporting cross piece I9 which in this case is a square tube, the inner surfaces of the cylinders I1 and i8 bearing on the corners 20, 2|, 22 and 23 (Figs. 7, 8 and 9) with only such-,i'riction as is necessary for the cylinders to remain in position after turning when tipping the slats or bringing them to horizontal positions.

Near the ends of the tube 9 are provided in the lower wall 24 thereof cross slots or openings 25 and 26 (Figs. 5 and 6), leaving cross bars 21 and 28 adapted to rest in brackets 28 and Ill secured to the inner i'acings of the window lambs. Intermediate the ends of the tube l9 the lower wall is also provided with openings II and 32 (Figs. 5 and 6) through which the ropes pass to the slats. At

suitable points there are connected to and between the side walls 33 and 24 (Fig. 6) of the tube l9, tubes 35, 36 and 31 over which the ropes slide and turn as is clear from Figs. 5 andfi.

The cylinders l1 and I I are provided with arc slots 38 and 28 of suiflcient length to permit the cylinders to turn when the slats are tilted in either direction, so as not to interfere with the rope passing through the openings II and 22 of the support I! and th slots 28 and 29 in the cylinders l1 and It. At the upper Part of the cylinders I! and II are struck up ears 40, 4!, 42 and 43 which may have apertures if desired for the passage of thread 44, 45, 46 and 41 sewed to the upper end portions of the suspendingtapes II and I2, these tapes being thus secured to the cylinders so that they will not crawl and throw the arc slots l2 and 38 out of proper angular relation to the ropes passing therethrough.

The supporting brackets 29- and III shown in Figs. 5 and 6 are of the form shown more in detail in Fig. 11. Each of these brackets comprises a wall plate 48 which is secured to the inner facing of the window jamb or the stop 3 or 4 thereon, by

any suitable elements, such as screws 4! (Fig. 5)

passing through holes 60 provided in the plate 48,

these holes being so located as to clear the ends 01 the side walls 23 and 34 of the supporting bar I! (Fig. 5). The lower edge of the plate 48 has an integral base flange ll which in tu n as e 9- wardly extending tongue 52 which extends upwardly in the slot 25 or 26 (Figs. 5 and 6). The width of the flange 5i between the tongue 52 and the plate 48 is the same as the width of the cross piece 21 or 28 of the tube I9, so that the cross piece 21 or 28 will fit closely in the bracket to prevent axial play of the tube I8, and also to seat squarely on the flange 5|. (Fig. 6). The upper corners of the tongue 52 may be chambered to facilitate the entry of the tongue in the slot 25 or 26 when the supporting bar or tube I9 is mounted in place. By reason of the tongues 52 being close to the edge of the cross piece 21 or 28, any tendency of the tube I9 moving linearly is prevented.

When the blind is to be mounted outside of the window frame, the type of bracket shown in Fig. 12 may be used. This bracket comprises a plate 48' having an integral right angle plate 4i! having screw holes 50 for receiving screws for securing the plate firmly to the outer facings of the window frame. Both plates 48' and 48 have integral reinforcing flanges 5| and il of which flange 5 I has an upstanding tongue 52' designed to perform the same function as tongue 52 of the bracket shown in Fig. 11. With the tube I! mounted in place on these brackets (Fig. 12), it will be apparent that should the tube l9 move linearly it will be impossible for either end of the tube l9 slipping out of place, the tongue 52 projecting up through the opening 25 or 26 and engaging the edge of the cross piece 21 or 28, preventing this to happen. In other words, the tongues 52, as also 52, lock the tube in place so far as horizontal movement of the tube i9 is concerned.

The means for contracting and for permitting the extension of the blind comprises ropes so connected to the sections as to effect successive contracting or extension of the sections of the blind. In the two section blind (see Fig. 4) rope 55 has an end 55 thereof connected (at the left) to the lowermost slat 1* of the first or upper section of the blind, and its other end 55 connected (at the left) to the lower slat 8 of the second or lower section of the blind. The other rope 56 has an end 56' connected (at the right) to the lower slat I of the first or upper section of the blind, and its other end 56 connected (at the right) to the lower slat 8 of the second or lower section of the blind. Both ropes are looped so that their looped porions 55 and 56 pass around a pulley i1 rotatably carried by a handle 58. In other words the rope 55 runs from connection 55* of slat 1' to and over tube 36, thence to tube 31. thence to loop 55, thence to tube 31 (second rope as shown in Fig. 4) thence to connection 55 of slat 8. Similarly rope 56 runs from connection 56' of slat l to and over tube 35, thence to tube 31 (third rope shown in Fig. 4), then to loop 56, thence to tube 31 (fourth rope shown in Fig. 4), thence to tube 85, and thence to connection 56" of shit I. From this it will be apparent that when handle 58 is pulleddownwardly, both ropes will move in unison because of the pull of the pulley 51 on the loops 55* and 58". The pull. being effected on both rope portions 55 and 56', will raise the bottom slat 1 of the upper section successively piling up these slats of this section. As the bottom slat 1* of the upper section is con nected to the suspension tapes Ii and I2, that slat accordingly lifts the lower section which remains in extended condition, that is, the slats of the lower section remain in spaced relation. The pull of the pulley 51 on the loops is such as to take up the rope portions to the lower slat 8 as it is raised with the other slats oi the All ' clip portion 16.

lower section. Fig. 2 shows the position of the slats after partial contraction of the upper section. Fig. 3 shows the position of the parts after the upper section has been completely contracted, and after the lower section has started to contract.

When the upper section is completely contracted, the rope portions running from the slat i to the loops 55 and 56 cease to continue movement, but continued pull on the loops by the pulley 51 causes the rope portions extending from the loops to the slat B to move thus causing an upward pull on the slat B and the piling up of the slats in the lower section. See Fig. 3 for showing this after partial piling up of the lower slats of the lower section. In Fig. 2 the dotted line position shows the full extended position of the blind and in Fig, 3 the lower dotted line position shows the half raised position of the lower section, and the upper dotted line position shows the full contracted position of both sections of the blind.

In Figs. 13 and 14 is shown a three section blind. In this case rope 60 runs from slat I (left end) by way of tubes 36 and 31 to a loop over pulley 51 thence to and over tubes 31 and 36 to slat 1 and similarly rope 6i runs from slat I to and over tubes and 31, thence to loop over pulley 51, thence to and over tubes 31 and 35, and thence to slat I. So far this is the same as shown in Fig. 4. To operate the lower slat 8, another rope B2 is looped through a ring 63 connected to the case of pulley 51 and the two laps of the rope 62 pass around pulley 5! and thence to and over tube 31, one of the laps passing over tube 36 and thence to the slat B, and the other of the laps passing over tube 35 and thence to slat 8 In operation a pull on the handle 58 first causes all the rope laps to move in unison, the slats l of the first section piling up, and the other sections rising in extended condition, until all the slats I of the first section are piled or packed. Then the ropes connected to the slats 1 and 8 move in unison, the slats I of the second section piling up while the third section rises in extended condition until all the slats 1 of the second section are piled up, then the rope laps of rope 62, only, move to pile up the slats of the third section.

By following the same system and compounding the pulley arrangement (SW-51 the blinds may be made to contract in any number of sec; tions.

The slats I are provided with elongated slots Hi to permit the passage of the ropes when the 4 slats are either in horizontal or inclined positions. At the slat I (and also 1 in the three section blind) the ends of the ropes 55 and 56 are secured to cleats II and 12 shown more specifically in Fig. 10. Each cleat has a body portion 13 provided with holes I4 and 15 through which pass the ropes 56 and 55. and a clip portion 16 made by bent over laterally extending portions. As shown in Figs. '7, 8 and 9, the end of rope 55 passes through the hole 15 and is clamped in the At the right hand end of the blind (Figs. 4 and 6) the end portion of rope 56 passes through the hole 15 of that cleat and is clamped in the clip portion 16. The companion rope 56 or 55 as the case may be, passes through the hole 14 and through the slots of the slats of the lower section, and has its end connected to a knob or ball 1'! located in a recess 18 formed in the lower slat B. The suspension tapes may be secured to the lower slat by suitable means, as tacks or the like 19 (Figs. 6 and 7) The cleat bears upwardly in simple contact with the under face of the slat 1 (Figs. 6, 7, 8 and 9) and is capable of sliding crosswise of the slat as the slat is tilted so as to accommodate itself to central position when the slat is tilted and as the ropes pull thereon and therethrough when operating the blind.

Since the slat I is designed to raise the lower section by way of the suspension tapes, extra cross tapes Bll are located above the slat 1 (Fig. 6) and are secured at their ends to the suspension tapes. When the slat I rises it lifts through the cross tapes 80 and the suspension tapes.

The handle 53 or 5i! may have means as a ring or hook 8| (Fig. 1) adapted to be engaged with any one of any number of hooks provided as desired on the jamb 2 (Fig. 1). The handle may also be weighted if desired, its weight being such as to counter-balance the weight of the slats.

In Figs. 15 and 16 are shown in schematic perspective, blinds with rope systems so connected and arranged that there is a looped rope for each section so that each section may be independently controlled by a looped rope.

As shown in Figs. 15 and 16 the lower slats I 1, and 8 of the first, second and third sections respectively are connected respectively to the two ends, BI, 82 and 83 of the looped ropes B4. 35 and 86 so that a pull on the looped rope 84 will lift the slat 1 rope 85 will lift slat 1 and rope 86 will lift slat 8 The rope ends BI and 82 are respectively connected to cleats 12 and 12 beneath the slats I and 1, and the rope ends 83 are connected to suitable means as knobs or knots beneath the slat 8 The cleats l2 and 12 are provided with suitable holes for the passage of the rope parts or segments running to the slats 1 1 and 8.

In Fig. 15 the rope 84 has a loop 81 with which is interlooped a loop 88 of rope B5, and in turn rope 86 has a loop 89 looping over a bend 90 of the rope 85, the latter having a bend iii.

In operation, (Fig. 15), to lift the blind and to contract the upper section only, all three ropes H4, 85 and 86 are pulled together. Slats I pack up and the second and third sections are lifted with the slats thereof in spaced relation. See dotted line position of slats I for fully packed or piled up position.

When slats I are fully packed up, further movement of the rope B4 ceases. The loop 81 may then be hooked under a pin 92 fixed in the side jamb of the window frame so as to hold the slats i in packed up condition.

Further pull may then be on ropes B5 and 86 together such that the bend 90 slides through loop 89 and lengthens out as shown in dotted lines in the lower left hand portion of Fig. 5. Siats 'l will then be packed up as shown in dotted lines in the upper part of Fig. 15. The bend 90 may then be hooked under a pin 93 fixed in the side jamb of the window frame.

Further pull may then be on rope 85 only, the bend 9| lengthening out as shown in dotted lines in the lower left hand portion of Fig. 15. This bend 9! may then be'hooked under a pin 94 fixed to the side jamb of the window frame. In this case the slats 8 will be packed up as shown in dotted lines in the upper part of Fig. 15.

The pulls above mentioned may be effected by placing the fingers of the hand in the loop 81, and the bends 90 and Bi. After hooking loop 81 under pin 92, then the fingers in bends 90 and 9| effect the pull on ropes 85 and 85, the rope B5 sliding around the finger in the bend 90 to lengthen out that bend, and later the rope sliding around the finger in the bend 0| to lengthen out that bend. 0n the other hand pulleys may be located in the loop 01 and bends 00 and 9| similarly to the pulley system shown in Fig. 13. While three sections are shown for 11- lustration it will be understood that the same system may be carried out as disclosed for a blind having any desired number of sections.

In Fig. 16 the ropes B4, 05 and 80 have their loops 95, 96 and 91 independent from each other and to them are connected pull cords 00, 00 and I00 respectively. The pull cords may be pulled together or independently as desired. The cords 98, 9B and I00 have loops or the like Illl, I02 and I03 for hooking under pins 02, 00, and 94 shown in Fig. 15. The operation is believed to be obvious.

In Figs. 1'? and 18 are shown alternate forms of brackets for supporting the head bar I0 corresponding to the bar I0 in Figs. 5 and 6. To one of the side jamb stops, such as stop 4,-is secured a plate I04 by means 01' screws I05. This plate has a lateral extension I00 capable of extending into the hollow member I! (as shown) for a sufllcient distance to act as a supporting ledge or the like for the end portion I0 of the member IS, the end I0 oi the member Iil abutting the suri'ace of the plate I04.

30 At the other end oi the supporting bar or head support I9" is provided a spring bracket comprising a plate having a base portion I01 secured to the stop 3 by screws I08, and a spring portion I09 having a laterally extending flange or ledge 35 H0 adapted to be located beneath the end portion I9 for supporting the same on the ledge I I0. The ledge IIO has an upwardly extending flange I II adapted to resiliently press against the end portion I0 of the bar Iii so as to maintain the 49 other end I9 in place on the ledge I06, the part III projecting up through a slot H2 provided in the upper wall of the bar I9 and at the end thereof as clearly shown in Figs. 1'7 and 18.

When assembling the bar I0 and the blind supported by it, the end (right hand end as viewed in Figs. 17 and 18) is pressed against the spring part III9III toward the stop 3 to such an extent as is necessary for the other end portion l0 to clear and be located above the ledge I06, and then the spring portion I00-III moves the bar I9 so that its end I0 abuts the plate I04 and the end portion I9" rests upon the ledge I08, the other end portion I0 then resting on ledge H0 and being abutted by the spring part III, as shown in Fig. 18. To remove the opposite operation is followed.
